Consensus decision-making seeks agreement from the group rather than a majority, which is a trade rather than a virtue.
Why it matters when the plan changes
Consensus produces decisions people actually implement, a real advantage over decisions imposed and quietly ignored. The cost is that every participant effectively holds a veto, so the pace of the whole is set by the most reluctant party, and a plan with time pressure can be defeated by a process nobody objects to. Cross-unit commitments are the weakest part of execution: Donald Sull, Rebecca Homkes and Charles Sull found only 9% of managers say they can rely on colleagues elsewhere all the time, and consensus is one attempt to make such commitments hold.
The tension is that consensus is rarely declared as a rule; it operates as a norm, so nobody decides which decisions require it. Looking past formal design to real ownership shows the norm applied without regard to the decision at hand. An organisation that needs consensus on strategy and speed on pricing will apply the same norm to both unless someone says otherwise, and the norm is usually invisible to the people inside it.
In practice
A group adopts a faster operating model and keeps its consensus norm. Pricing decisions that the new model assigned to a single owner continue to be taken to the leadership meeting, because that is how decisions are made here. The structure changed and the norm did not, and the norm is what determines the pace.
Evidence
Consensus decision-making seeks the agreement of participants rather than a simple majority.

What it cannot tell you
Consensus culture describes how decisions are expected to be reached; it does not indicate which decisions actually need broad agreement and which need speed. The term is silent on whether an organisation has ever named that distinction, so a culture can be functioning exactly as designed and still be applying agreement to matters where it is simply the wrong mechanism.
Questions
Not in itself. Consensus produces decisions people actually implement, which is worth a great deal given that Donald Sull, Rebecca Homkes and Charles Sull found only 9% of managers say they can rely on colleagues in other functions all the time. It becomes a problem when applied uniformly, including where speed matters more.
Consensus reaches a decision people own; stalling reaches no decision and everyone describes it as still being worked through. The difference is whether there is a point at which the discussion ends with or without agreement, and whether anyone has the authority to call it.
The norm shifts slowly. What can change quickly is which decisions it applies to. Naming a small set of decisions that will be made by a single owner, and saying why, works better than attempting to change how the organisation decides in general.
It reflects broader norms about hierarchy, participation and how authority is legitimised, reinforced in some countries by formal employee participation rights. It is a feature of how those organisations actually work rather than a deficiency measured against more directive cultures.
Either the norm holds and the decision arrives late, or it breaks and the decision is made without the agreement that Consensus decision-making, as defined by Wikipedia in 2026, is built to produce. Both outcomes are worse than deciding in advance which classes of decision suspend the norm and saying so plainly.
